Vulcanizer is a special stage available on the 6th of every month if the player has previously completed all Crazed Cat stages. Completing this stage unlocks the True form of Crazed Tank Cat. Using Cat Food to continue the battle is not allowed in this stage.
Bring Rich Cat, Sniper Cat, and Cat CPU.
The use of 5 meatshields is pretty much not an option. One of the main problems is the buffed Gory Blacks that rush you in the beginning. Ururun is the best way to kill them, because of her fast attack. Manic Eraser has nearly 5 million health; therefore, it will take a while to kill him. Chip at his health with a stack of King Dragons or Prisoners alongside Bahamut Cat, while stalling the enemies using Ururun and Dark Emperor Catdam's status effects. Use Crazed Sexy Legs when Capy is out to deal damage to the Owlbrows from outside of the boss's range.
If a player is willing to use Ubers, one can bring Ultralan Pasalan to replace both Ururun and Catdam, and Bahamut with the God-Emperor Megidora, Vars or Kamukura, cats who all have better DPS and health along with status against boss support. Crazed Legs and King Dragon may be replaceable by stronger DPS units like Divine Thundia.
If you're lucky enough to have him, Super Galaxy Cosmo makes the level a lot easier. You can easily stack him to kill the support units behind the Manic Eraser.
Having Shishilan Pasalan can make quick work of Manic Eraser, outranging him and having a high damage output. Be sure to have proper shielding in front of it!
